﻿460 THE BLEA-WYKE BEDS IN NORTH-EAST YORKSHIRE. [Aug. I905, 



found at Blea Wyke and at the base of the Dogger elsewhere, in the 

 sense in which it was employed by the older writers, as a purely- 

 descriptive term, and fully agreed that many of these 'pebbles' were 

 concretionary. He had drawn the base of the Dogger at Blea Wyke 

 below the J^erincea-'Bed, so as to bring it into line with the thickness 

 observed at other sections. He was quite aware that ammonites 

 were fairly abundant at Blea Wyke, as stated by Mr. Hudleston, 

 but were rare elsewhere. As Mr. Herries remarked, fossils were 

 abundant at some of the other sections described, but their manner 

 of preservation rendered identification difficult, except at Glaisdale, 

 where the fauna was large and comparatively well-preserved.
